• Aqueous phase reforming (APR) of xylitol.
• Comparison between Pt/Al2O3, Pt/TiO2 and Pt-Re/TiO2.
• Influence of Re on stability, activity, product formation and selectivity.
• Higher selectivity to alkanes on Pt-Re/TiO2.
• Plausible reaction scheme proposed.
The aqueous phase reforming (APR) of xylitol was studied in a continuous fixed bed reactor over three catalysts: Pt/Al2O3, Pt/TiO2 and Pt-Re/TiO2. The data obtained in the case of the monometallic Pt catalysts was compared to the bimetallic Pt-Re sample. The effect of Re addition on the catalyst stability, activity, product formation and selectivity toward hydrogen and alkanes was studied. The bimetallic catalyst demonstrated a higher selectivity to alkanes compared to the monometallic samples. The monometallic catalyst was more selective toward hydrogen formation. A plausible reaction scheme explaining differences in selectivity toward hydrogen and alkanes was proposed and discussed.
